Last spring my PS2 broke down, big surprise there. CD games booted fine but DVDs didn't. The laser was obviously shot so I ordered a new one. After it arrived, we installed it but I still have problems. Here's what's happened so far. 1. When we booted the PS2 all we heard was a grinding / ticking sound. We diagnosed this as the white guiding arm not making proper contact with the snake motor and bended it down a bit. That got rid of the problem and now DVD movies and CD games worked perfectly. 2. Even now DVD games refuse to boot. We've tried backups, originals, several different games. None boot. We get a weird gurgling kind of noise. Around the time when the star field fades into the "Browser / system settings" menu the PS2 makes two loud ticks and then pretty much stops spinning the disc. We've tried adjusting the tiny screw, we've tried adjusting the white cog, we've tried greasing the axles the laser runs on, nothing helps. I can't even begin to imagine a problem that would cause DVD games to fail when DVD movies and CD games (even backups!) boot perfectly. I'm getting a new PS2 to replace this one but I'd like to get the old one up and running because the new laser + modchip set me back quite a bit. ANY help would be appreciated.
